Ideally suited for the high speeds required of drilling extremely small holes in PCB materials, typically down to 0.1 mm diameter, while still delivering sufficient power at low speeds to drill 6.3 mm tooling holes. The PCB Drilling & Routing Series Spindles deliver smooth, precise rotation that enables maximum tool life and excellent hole quality. Very low runout ensures accurate hole placement. Integrated non-contact axial and radial air bearings guarantee long service life with minimal maintenance and very low heat generation. Highly reliable water-cooled AC induction motors are fitted into every spindle. Mature design based on extensive experience and expertise, accompanied with state-of-the-art manufacturing, enables reliable operation and long product life.
